A
Everybody hates rats. But in the earthquake capitals of the world — Japan, Los Angeles, Turkey — rats will soon be man's best friends.
What happens after an earthquake We send in rescue dogs.Why？Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work First, the rat is trained to smell people. When this happens, the rat's brain gives a signal (信号)．This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “Robots' noses don't work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn't get to, and a rat would get out if it wasn't safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course)．

After an earthquake most survivors can be expected to recover over time, particularly with the support of family and friends. Some families will be able to return to their normal life quickly, while others will have to contend_with the destruction of their homes, medical problems, and injury to family members. Children especially will need time to recover from the loss of a loved one or a pet or from the closing down of their school.
Children often turn to adults for information, comfort and help. Parents should try to remain calm, answer children's questions honestly and remain understanding when they see changes in their children's behavior.
Children react differently to an earthquake depending on their ages, developmental levels and former experiences. Some will respond by withdrawing (不与人交往), while others will have angry outbursts (爆发)．Parents should remain sensitive to each child's reactions. Parents should spend time talking to their children, letting them know that it's OK to ask questions and to share their worries. Although it may be hard to find time to have these talks, parents can use regular family mealtimes or bedtimes for them. They should answer questions briefly and honestly and be sure to ask their children for their opinions and ideas. Issues may come up more than once and parents should remain patient when you answer the questions again. For young children, parents, after talking about the earthquake, might read a favorite story or have a relaxing family activity to help them calm down. Parents should also tell children they are safe and spend extra time with them. They could play games outside or read together indoors. Most importantly, be sure to tell them you love them.

Last weekend, I was in North Lake Tahoe area and was stuck in a snowstorm. I decided to stay back and planned to do something that I never did before. It was to just walk in the snowstorm along CA－89 as much as possible feeling adventurous about it. During my adventurous walk, I met the following types of people：
Concerned couple
About two tenth of a mile into my adventurous walking, a car was approaching me and it stopped and a couple rolled down the window and asked me if I needed any help. I said “I'm Snowshoeing”， they_laughed_their_ass_off and moved on. This “concerned couple” reminded me that no matter what the environment is, ask if you could assist others as much as you can.
Smiling girl
About 2 miles into my adventure, I was feeling very cold and started to head back to the cottage where I lived. When I turned around, about a quarter mile away I saw what it appeared to be a beautiful girl. As we saw each other face to face she just smiled and looked at me as though she knew of my adventure. This “smiling girl” reminded me that no matter what the environment is, never forget to smile and acknowledge others.
“A cool” group
About an hour into my walk, past the smiling girl. I saw a group of happily driving skiers in their off road SUV. As their vehicle approached me, they started to slow down and said “Man, what the hell are you doing walk in a snowstorm？” I said, “Checking how much more I could take of it”. This group reminded me that no matter how happy you are, never forget to ask what others are doing.

Having lived in California until 1970, my family has felt a number of earthquakes. We have been fortunate, however, to have suffered no bodily harm or property damage.
There is a website that lists all California earthquakes recorded from 1769 to the present. The site lists the dates and times as well as the magnitude (震级) and the exact location of any quake that measured more than 6.0.There are only a few quakes that stand out in my memory and, luckily, none is shown in the website. So, my personal experience with earthquakes might be considered insignificant.
There are three earthquakes that are difficult to forget. The first one was in 1955 and our oldest daughter was walking with me in our backyard in Redwood City in California. As the shaking became stronger I held her to me with one arm as I held on to one of our fruit trees with the other. All three of us (my daughter, I and the tree) shook for two or three minutes that to us felt like hours.
The second one was in 1963. Our entire family was visiting Disneyland in Southern California. The earth started to shake just as we were beginning to walk from our hotel toward the_famous_landmark.
My third experience with an earthquake was a lonely one in California. It was in my sixties and I was alone in an old church. As the building started to shake, I quickly headed for the door to go outside. I remember I said a little prayer — something like, “Help me get out of here in time, Dear Heavenly Father”．Minutes later, I was safe outside.

解析：选D 细节理解题。根据第三段的“The first one was in 1955...in California.”和第四段第二句以及第五段的“My third experience with an earthquake was a lonely one in California.”可知答案。

Warming Up & Reading — Pre-reading
阅读理解
A
If the crust (外壳) of the earth were not pretty solid (坚固的), it would be shaking about and moving up and down frequently. However, there are places in the rocks of the earth's crust where it isn't strongly held together — where faults exist. Along the faults, one rock might push against another with great force. The energy is changed to vibration in the rocks, so they begin to shake and we have an earthquake!
The most famous one in North America was the San Francisco earthquake of 1906.Seven hundred people died and property (财产) damage amounted to about D|S425,000,000.The greatest destruction came from the fires that followed the quake.
One of the most famous earthquakes in Europe took place in Lisbon, Portugal, in 1755.The city was destroyed and at least thirty thousand people were killed. In 1908, in Calabria and Sicily, a quake killed about seventy five thousand people. In 1915, in central Italy, hundreds of towns and villages were damaged and thirty thousand people were killed.
Two great earthquakes that caused great damage in Asia took place in Tokyo, Japan, and in Gansu Province in China. The Tokyo quake of 1923 killed more than one hundred thousand people and destroyed the city and the city of Yokohama, too. The Chinese quake in 1920 covered more than three hundred square miles and killed about two hundred thousand people.
语篇解读：本文介绍了地震起因及历史上几次大地震。
1．The first paragraph mainly tells us________.
A．where earthquakes happen
B．how earthquakes happen
C．the damage caused by earthquakes
D．famous earthquakes in the world
解析：选B 段落大意题。通读第一段可知，本段介绍了地震的起因。
2．The underlined word “vibration” in the first paragraph probably means “________”．
A．shaking B．force
C．energy D．losing
解析：选A 词义猜测题。一块岩石有可能用力挤压另一块岩石，地壳的能量发生了改变导致岩石晃动，于是地震发生了。vibration意为“晃动”，故A项正确。
3．We can infer from the passage that________.
A．the earth's crust in Europe is weaker than that in other places
B．the fires following the San Francisco earthquake caused more damage than the earthquake did
C．there were 75,000 people killed in the San Francisco
earthquake
D．the city of Yokohama was not greatly influenced by the Tokyo quake
解析：选B 推理判断题。由第二段“The greatest destruction came from the fires that followed the quake.”可推知B项正确。

When people want to know about the weather, they usually go to their radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure (压力) produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around. Deer leave high ground and come down from the mountains.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable (急躁的) and quarrelsome and will fight over a piece of bread. Other birds chirp (叽叽喳喳) and sing just before a storm. It seems that they know they won't get another chance for an hour or two. Birds also seek safe places before a storm. You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre storm low pressure makes the air so thin that birds have difficulty flying.
It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm.
By paying closer attention to some important signs in nature, we can become better prepared for any kind of weather.

Earthquakes strike suddenly at any time of the day or night, but there's no way to tell when. If an earthquake happens, it may cause many deaths, injuries and damage. So you need a good preparation ahead of time. Decide how and where your family will get together if separated. Choose an out of state friend or relative that the family members can call after the quake to report where they are and how they are. Know the safe places in each room: under the strong tables, desks, or against inside walls. Keep enough food, water and other things, including a flashlight, a radio, medicines and clothing.
During the earthquake, you should keep a clear head and never be too nervous to know what to do. Protect your head and neck with your arms. If possible, take a book, a pillow or any other things to protect yourself from falling glass and ruins. If you are indoors, you must immediately lie under any strong furniture. If outdoors, move to an open area away from trees, buildings, walls or powerpoles. If you are in a narrow valley, move to the centre of it and look up for falling stones. If you are in a car, move to the side of the road and stop the car. Do not stop near buildings, power lines or on or under bridges. Stay in your car until the shaking stops.
Do not move a badly injured person unless he is in great danger after the earthquake. Do not use the telephone immediately unless there is a serious injury or fire. Turn on your radio for instructions and news reports. Be prepared for aftershocks. If you want to leave your home, post a message inside your home telling your family members where you can be found.
